In yet another tale of past sexual abuse of children at pricey Northeast private schools, a former student at Connecticut’s Kent School is alleging that administrators failed to protect her from a predatory teacher in the late 1980s.

The former student contends in her suit that she was a 15-year-old sophomore back in 1987, when she was seduced and repeatedly abused on school property by a married French teacher who was around 50 years old.

The lawsuit names the teacher as Clyde Douglas Fenner; the Post is withholding the name of the woman, who is also identified in the suit. Fenner did not return a call from the Associated Press seeking his comment.

The lawsuit alleges that Fenner groomed the student by confiding details about his life, writing her letters, and taking her on trips off campus; their first “sexual relations” was on the floor in the Kent French department, the New York Times said in its account of the suit.

The suit also alleges that two faculty members who knew of the abuse did nothing to stop it, and that while Fenner was forced to leave the school, he was not prosecuted and was able to get another teaching job in Evansville, Ind.
